Abstract From the New Y-Chromosome Haplogroup Tree Article

Here is the abstract of today’s Y-chromosome haplogroup tree paper in Genome Research, I’m still working to get a copy of the actual paper (unfortunately, it’s not open access at this time):

Markers on the non-recombining portion of the human Y chromosome continue to have applications in many fields including evolutionary biology, forensics, medical genetics, and genealogical reconstruction. In 2002, the Y Chromosome Consortium published a single parsimony tree showing the relationships among 153 haplogroups based on 243 binary markers and devised a standardized nomenclature system to name lineages nested within this tree. Here we present an extensively revised Y chromosome tree containing 311 distinct haplogroups, including two new major haplogroups (S and T), and incorporating approximately 600 binary markers. We describe major changes in the topology of the parsimony tree and provide names for new and rearranged lineages within the tree following the rules presented by the Y Chromosome Consortium in 2002. Several changes in the tree topology have important implications for studies of human ancestry. We also present demography-independent age estimates for 11 of the major clades in the new Y chromosome tree.

    I can forward you a copy of the article if you like. Just let me know.

    The article doesn’t include any of the “supplemental” charts and where all of the detail is.. Don’t waste your $..

    “Clade R
    Haplogroup R is identified by eight mutations: M207, M306,
    P224, P227, P229, P232, P280, and P285 (Supplemental Fig. 16).
    A total of 42 mutations identify 28 subclades nested in clade R.
    This compares with a total of one defining and 16 internal mutations
    for this clade in 2002. The majority of European Y chromosomes
    belong to this clade.”

    Supplemental Fig 16 not included or available..

    I can’t find any of the supplementary information either, very frustrating!

    Since this article was published online in advance of the entire journal, the supplemental material is not yet available. It should be available (for free at http://www.genome.org) when the entire May issue is published online.
